DISTILLING APPARATUS.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed May 4, 1903. Renewed October 23, 1906. Serial No. 340,186.

To aZZ whom, it may concern.-

Be it known that I, PHILLIP J HOPE, a citizen of the United States, and a resident of Everett, in the county of Middlesex, State of 5 Massachusetts, have invented certain new and useful Improvements in Distillin Apparatus, of which the following is a ful clear, and exact description.

The object of my invention is the construction of an improved apparatus to be used in the manufacture of varnishes, the primary object thereof being to prevent the loss of the hydrocarbons and volatile ingredients of'the varnish. Referring to the drawing, forming part of this specification, and which shows the complete apparatus in a central sectional elevation, the reference-numeral 1 designates the varnish-pot, and the cover thereof; designed to be tightly secured thereon by suitable clamps 7. Secured upon this cover is the cylinder 11, of which said cover constitutes ,a bottom, and both form a Water-tank. Within this tank is a coil 13, whoseupper section is joined to the upright vapor-discharge 12 and whose lower section termi nates in the tail 14 outside the water-tank.

Flowing water is received into this tank from any suitable source, as a pipe 15,held above 39 it, while the water overflows through the overflow-pipe .16 at the upper edge of the tank. "A pipe 17, normally closed by a cook .18, enables all the water to be drawn from the "tank [when desired. This combined cover and still having been clamped upon the pot 1, the vapors arising from the contents escape through the discharge 12 and passing therefrom through the coil or worm13 are condensed'by the surrounding water and drip -from the worm-tail 14 into any suitable rece tacle.

' ithin the pot 1 I locate the stirrer, consistingof the vertical shaft 2 and stirrerarms 3.,1the same being revolubly supported by means of the collar 4 and the metal crossstrap 5, Whose ends are detachably held by the pins 6, projecting from within the pot. Said strap is of course suitably apertured to permit the shaft 2 to pass through it and said collar to rest upon the strap.

Within the tube 23, which is rigidly held by the cover 10, is the rod 21, havin turning handle 20 at its upper end and a soc et 24 at its lower end. This socket fits loosely the upper end of the shaft 2 and both are made rectangular or prismatic in order that the ro-= tation of the rod shall turn the said shaft with it. Moreover, this socket is made deep .enough so that in case the stirrer-arms 3 are forced to rise over a hummock or other hard accumulation of varnish the end of said shaft has ample play to ascend in saidsocket while still being made to turn therewith.

. The upper end of the socket 24 and the under face of the collar 22 at the upper-end of the tube 23 are each made conical in order to close the said tube and prevent the escape of vapor through it. After the mixing operation is com lete the combined cover and still are raised om the pot and swung to one side by any suitable block and tackle, the socket 24 releasing the shaft 2 as the parts are raised. In the same manner as the cover and still are returned to their osition over the pot and 7 5 ,lowered down t ereon the socket 24 receives the shaft end with certainty, andafter the rims have come together the clamps 7 are a plied and the cover made fast.

Alt ough it is customary to remove the tankor pot to the reducing-room before adding the hydrocarbon, my apparatus enables me to do the entire work Without removing the apparatusfrom the fire. This is possible, for the reason that there areno explosivevapors thrown ofi into the airjbut,- the condensed hydrocarbon passes off from" the worm through a suitable pipe to a place of safety, and the turpentine or other hydro- 1 carbon used is fed to the mixture in the pot through a pipe 19 from a distant reservoir. Thus at no instant is there any exposed inflammable liquid or explosive vapors in danger from the firewhich is heating the mixture. On this account I am enabled to work with far better efficiency with my apparatus than in the former methods, since the point to be guarded against in the old manner of workin lay in the mixture becoming too cool before theproper treatment had been effected. Now, however, I can keep the mixture up to the right temperature until the work is entirely finished and the completed varnish ready to be umped up to the receiving-tanks in the ot er part of the establishment. Another great gain accomplished by my apparatus consists in the freedom given to the workmen from the sufiocating fumes or vapors rising from the .hot hydrocarbon. Not only are they practically blinded by the vaporespecially when turpentine is the hydrocarbon -used IIO but the men are often made fairly drunk by the same, and so are incapacitated from properly looking after the Work. Hence it often happens that the varnish is absolutely ruined from this cause alone.

That I claim as my invention, and for Which I desire Letters Patent, is as follows, to Wit:

The combination with a varnish-kettle, of a cover removably secured thereto, a cylindrical shell fixed Water-tight at its lower edge to the upper surface of said cover, means for admitting Water thereto and removing it therefrom, a tube fixed Watertight to said cover and rising centrally Within V said cylindrical shell, a shaft permanently but rotatably located in said tube and having a turning handle at its upper end and a clutch member at its lovver end within said kettle, stirrers rotatablysup orted in said kettle and engaged by said 0 utch member,

a Worm located in said cylindrical shell concentric With said tube and communicatim at its u per end with the interior of said kettle t ough said cover and at its lower end radially through said shell, and a pipe for the introduction of hydrocarbons through said cover into said kettle; said pipe having means for its closure.

In testimony that I claim the foregoing invention I have hereunto set my hand this 2d day of May, 1903.
